To test a three-phase induction motor, you can use a multimeter to check for continuity, insulation resistance, and voltage imbalance.

• Use a multimeter to check for continuity between the motor windings and the motor frame

• Measure the insulation resistance between each winding and the motor frame to ensure there are no shorts

• Check for voltage imbalance by measuring the voltage across each phase of the motor
